Megophrys parva (Boulenger, 1893)

Found on Mt. Tay Con Linh II on banks of streams and in nearby forest (within 4 m of streams) from 1400 m. Males called strongly from under leaves and the hollows of rocks and logs. This species is known from Nepal east to Yunnan, China, and south to Tenasserim ( Myanmar) ( Frost, 2002). Megophrys parva was recently found in northwestern Vietnam (Ohler et al., 2000) and this is the first record of it east of the Red River in Vietnam. It is probably contiguous with other Yunnan populations.

Amolops chapaensis ( Bourret, 1937)

Figure 5

This species was common between 800 and 1700 m on Mt. Muong Cha and Mt. Tay Con Linh II. It was found associated with fast­moving water: among cascades, in splash zones, on mossy boulders midstream, along wet, rocky walls, and in streamside forest to 3 m. Males had distended vocal pouches and females were gravid.

This species has been recorded from the type locality in Sa Pa , Lao Cai Province, Vietnam, and from Yunnan Province, China ( Fei, 1999). This is the first Vietnam record east of the Red River .
